HELP: cam for TPI/HSR

ok, i decided if i can drop $500 for cams for my hayabusa... i can spent $100 on a cam for the car . right now as the car sits, it has a TPI intake on it. which is ok.. but i SERIOUSLY need 2 get that HSR for her to breath. so im wondering what cam i should do in the mean time.

im looking at a (236/242, .520/.540) *dont know what LSA i want.. thinking either 112 or 110. but its based off of 1.5 RR... and i do have 1.6's * but im debating on if i should get a "better" cam more ment for a HSR and install it now, or just get a decent cam for the TPI now, and when i get my HSR, get 1 then. im also going 2 switch from AFR 195 heads 2 AFR 220's when i get the HSR.

any help would be appreciated, and and other cam sizes would be appreciated as well.

ok here are the "specs" for the cams im looking at...
none say their @ .050 though.. or they do and im missing it. either way, the 2nd 1 is looking the best cause of the lift, but #3 is a bit better cause of the powerband (then again, i plan on getting a HSR and 220 heads) so maybe the 2nd cam will b better 2 "deal" with for a while.

this 1 i think is more for bracket racing

and these 2 are more for computer controlled cars

What cam do you have in it now and what are you looking for from the swap? Your et and mph is pretty screwed up. I'm assuming that et /mph was on the spray,, so it looks like you need to work more on the suspension getting what you already have to hook up.
